NEW! Variprop GP
14% Greater Performance
Get up to 14 percent greater performance and extended cruising range with the new Variprop Grand Performance (GP) feathering propeller. For shaft and saildrives.
Aero Foil Shaped Blade
The only feathering propellers on the market with Gawn blade profile (aero foil shaped blade). The Gawn profile blade is more efficient, producing no vibration when motoring and very low drag under sail.
14% Reduced Fuel Consumption
SPW’s innovative design of the Variprop GP has achieved up to 14% reduction in fuel consumption while also delivering high thrust, extending your cruising range and reducing CO2-emissions.
The all new Variprop Grand Performance (GP) propellers are based on the company’s proven technology and provide ever better performance, reliability, efficiency, fuel efficiency and longevity in all conditions.
Unique Variprop Features
A. Independently adjustable external pitch control. Forward and reverse pitches can be changed in just seconds — even underwater.
Benefits: Custom fine tuning (in micrometer-small increments) of reverse thrust vs. prop-walk. (For most owners, eliminating prop walk is more important than maximizing reverse thrust.)
VARIPROP allows you to customize that balance for optimum control, maneuverability and safety. Independent fine tuning of forward thrust means that VARIPROP delivers the best possible performance (speed, thrust, fuel economy) in forward without compromising reverse performance – and vice versa
B. SoftStop™ shock absorber – Shock Absorbing Multidisc Brake (patented) built into the VARIPROP hub.
Benefits: Dramatically reduces shock loads on gearbox and drivetrain, permits shifting at higher speeds without damage, preserves preset pitches by eliminating hard limit stop impacts (the typical “clunks” of all others). The entire drive train benefits: longer cutless bearing life, minimized wear on gearbox, clutch plate, bearings.
SoftStop™ shock absorber lets you shift smoothly and extends the longevity of the whole drive.
Quality Construction
All propellers sold by AB Marine are manufactured from NIBRAL, a metal alloy made of nickel, aluminum and bronze. NIBRAL is far stronger in all specification areas than manganese bronze (commonly used by other prop manufacturers).
